U+1F5F5 Ballot Box with Script X

El Wikipedia tiene la siguiente información acerca de este punto de código:

A checkbox (check box, tickbox, tick box) is a graphical widget that allows the user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options. For example, the user may have to answer 'yes' (checked) or 'no' (not checked) on a simple yes/no question.

Checkboxes are shown as empty boxes when unchecked, and with a tick or cross inside (depending on the graphical user interface) when checked. A caption describing the meaning of the checkbox is normally shown adjacent to the checkbox. Inverting the state of a checkbox is done by clicking the mouse on the box, or the caption, or by using a keyboard shortcut, such as the space bar.

Often, a series of checkboxes is presented, each with a binary choice between two options. The user may then select several of the choices. This is contrasted with the radio button, in which only a single option is selectable from several mutually-exclusive choices.

Checkboxes may be disabled (indicated "greyed out") to inform the user of their existence and possible use despite momentary unavailability.
